SPEGIFICATION forming part of Letters Patent No. 5 11,897, dated July 2, 1895.

Application filed March 11, 1895. Serial No. 541,Z46. (No model.)

To aZZ whom it may concern:

Be it known that I, HARRISON H. TAYLOR, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement inSteam-Boilers; and I declare the following to be a full, clear, and exact deent filed by me November 15, 1891, Serial No.

My present invention consists of the construction, combination and arrangement hereinafter described and claimed and illustrated in the accompanying drawings, in Which Figure 1 is an end elevation showing a portion of the structure in section. Fig. 2 is a cross section at right angles to the view shown in Fig. 1. Fig.3 is a detail view of one of the Y-shaped couplings and its connections, Fig. 4 is a detail view in section showing the nipple connection of certain parts of the structure. Fig. 5 is a view similar to Fig. 2 showing a modification.

The purpose of my present invention embodies the construction of a steam boiler of greater heating capacity, as well as of a boiler of simple construction, whereby the heat will be utilized to the greatest degree in the generation of steam thereby.

I carry out myinvention as follows:

In the drawings, A denotes a series of vertical pipes located immediately above the combustion chamber 13 of the boiler, said pipes uniting, in a manner hereinafter described in a manifold A at their lower ends, the upper extremities of said pipes uniting, as hereinafter set forth, in a manifold A A Figs. 1 and 2, denotes an additional se: ries of vertical pipes above the manifold A connected into said manifold A at their lower extremities, the upper end of said pipes A connected into a manifold A The vertical pipes A, Fig. 5, and A, A Figs. 1 and 2, are arranged, respectively, in rows across the boiler above the combustion chamber, said pipes, together with their respective manifolds, constitutinga header above the combustion chamber.

The Vertical pipes A and A are connected at their extremities in a manner analogous to that shown and described my above mentioned application. Thus with the upper ends of the pipes A are engaged a series of couplings, certain of said pipes being connected with T-shapedcouplings a,other of said pipes being connected with cross-shaped coup lings a. These coupling are shown in detail in section in Fig. 4, wherein, also, adjacent ends of the couplings are connected by an interior revoluble nipple a said nipple provided'with right hand screw threads at one end and with left hand screw threads at the opposite end, screwed into the correspond.- ingly threaded ends of the adjacent couplings. By this means it will be evident the two adjacent couplings may be drawn up tightly end to end, so that the corresponding pipes may be arranged near together, to form a large compact heating surface. contemplate forming of malleable castings, a coupling being employed at each end of said pipes. The pipes A are connected at their two extremities in like manner, either with T-shaped couplings a or with cross-shaped couplings a. The series of couplings a a at the extremities of the pipes A and A thus connected form the corresponding manifolds A, A and A The lower ends of the pipes These couplings I A, and the upper ends of the pipes A are manifold D at the side of the combustion chamber.

E denotes a series of pipes led through the combustion chamber connected at their upper ends into the manifold A by means of couplings a and at their lower ends into a corresponding manifold D, there being preferably two ofsuch manifolds D as indicated in Fig. 1, running lengthwise below the combustion chamber, and two of the lateral manifolds D also as indicated in Fig. 1. At one end of the boiler the manifolds D and D are connected by a pipe D indicated in dotted lines in said figure.

As shown in Figs. land 2, the header is constructed of the vertical pipes AA and their respective manifolds A, A and A", while in the modification shown in Fig. 5 the pipes A and the manifolds A are omitted, the header shown in said Fig. 5 simply employing the set of pipes A with their manifolds A and A at the top and bottom thereof. In the header illustrated in Figs. 1 and 2, the header is made of adouble set of vertical pipes, where increased capacity is desired.

Above the header is a dome F into which the manifolds D communicate at one end of the boiler through pipes D and at the opposite end of the boiler through pipes D.

B denotes the grate in the combustion chamber.

B is a bridge wall.

B is the inclosing case.

Toward the front and rear of the boiler as embodied in Figs. 1 and 2, my invention contemplates spacing the tubes 0, A and A apart, to form front and rear draft dues G and G. Toward the middle of the boiler shown in Figs. 1 and 2 Iomit aportion of the manifolds A pipes a leading from the manifolds A directly to the manifolds A the pipes at being practically an integral union of pipes and A without any manifold A intervening. By omitting some of themanifolds A toward the middle of the boiler, as above stated, I provide practically a draft passage Q for the passage of the products of combustion therethrough.

Adjacent to the manifolds A in the dues GG,I locate baffle plates G and G by which the draft is turned centrally inward toward the draft passage Q. I contemplate locating the manifoldsA so closely together as to compel the products of combustion to pass under the fines G and G. So also the manifolds A are located in like manner so as to compel the products of combustion to pass inward from the flues G and G to said draft passage Q. The manifolds A are also located so closely together as to compel the products of combustion passing outward thereunder from the draft passage Q to the flues G G as indicated by the arrows. In this manner, and by this construction the products of combustion are compelled to traverse through the pipes crosswise, or at right angles to the pipes so as to bring the heat into contact with the pipes and manifolds to utilize the heat to the fullest possible degree, thereby increasing the heating capacity of the boiler in large meas ore, and also permitting it to be constructed in the mostcompact form. The upright pipes obstruct and hold the heat. sufficiently to allow the heat to be thoroughly taken up by the water in the pipes. The same principle is carried out, so far as certain features of con struction are concerned, in the modification shown in Fig. 5. In the latter figure provision for a single return of the draft is disclosed, while in Figs. 1 and 2 provision is made for a double return of the draft as shown in Fig. 5. A portion of the manifolds A to the rear end of the boiler. is omitted forming a draft and 2 an additional horizontal return flue is provided.-

The pipes C and E are connected into corresponding manifolds by means of Y-shaped couplings H connecting two adjacent pipes into the manifold. The use of said couplings, it is evident, dispenses with the necessity of tapping the manifolds as much as would otherwise berequired. The upper manifolds of the header are connected into the dome F also by means of Y-shaped couplings H, a single coupling connecting two adjacent upper manifolds with the dome, by intervening pipes h leading into the manifolds and a pipe h leading from the coupling into the dome.

The upper manifolds directly beneath the dome, I prefer to lead into the base of the dome as shown, the pipes h projecting upward therewithin above any condensed water there may be within the dome. manifolds, not directly beneath the dome, F, I prefer to lead into the dome at the ends thereof as by the connecting pipe 77. leading from the corresponding couplings.

I prefer to locate within the dome, above the pipes h a partition J to divert the steam laterally therewithin. The pipes D and D preferably lead into the dome beneath said partition.

K is a dry pipe. r

In the form shown in Fig. 5 there is but one vertical flue at the end of the boiler, outside the header, indicated by the letter M analogous to one of the dues G G. Shown in Fig.2.

What I claim as my invention is 1. In a steam boiler, the combination of vertical pipes, and manifolds having a screw threaded connection with said pipes at the upper and lower ends thereof and communicating therewith, said manifolds located closely together forming a horizontal return draft flue therebetween, substantially as set forth.

2. In a steam boiler provided with a vertical flue at one end thereof, the combination The upper of vertical pipes, and manifolds having a screw threaded connection with said pipes at the upper and lower ends thereof and communicating therewith, said manifolds located closely together forming an intermediate horizontal draft flue communicating with said vertical flue, substantially as set forth.

3. In a steam boiler, a series of vertical pipes having manifolds at the extremities thereof constructed of T-shaped and crossshaped couplings, the adjacent manifolds at the top and bottom of the pipes arranged in,

close proximity to compel the products of combustion to pass therebetween, substantially as set forth.

In asteam boiler, aseries of vertical pipes A and A a series of manifolds therebetween, and at the lower extremities of the pipes A and at the upper extremities of the pipes A said manifolds made of T-shaped and crossshaped couplings, the adjacent manifolds closed therebetween forming intermediate draft flues, substantially as set forth.

5. In a steam boiler, a series of vertical pipes having sets of manifolds at the upper and lower ends thereof, each set of manifolds located closely together and arranged to compel the products of combustion to pass about one set of said manifolds and to return under the other set of manifolds, substantiallyas set forth. 6. In a steam boiler, the combination of pipes A, sets of manifolds A A into Which the extremities of said pipes are connected, a set of manifolds A pipes A connected into the manifolds A A said pipes and manifolds arranged to form a header above the combustion chamber of the boiler, each set of manifolds closed therebetween, substantially as and for the purposeset forth.

7. In a steam boiler, the combination of pipes A, manifolds A A into which the extremities of said pipes are connected, a manifold A pipes A connected into the manifolds A A flues G G toward the ends of the boiler,

- means to close said flues adjacent to the maniends of said pipes, lower manifolds at the base of the pipes A, upper manifolds at the upper ends of the pipes A manifolds below the combustion chamber, pipes connecting the manifolds above and below the combustion chamber, a dome, Y-shaped couplings connecting the upper manifolds into the steam dome, and

the lower manifolds with the adjacent pipes,

and pipes connecting the lower manifolds into the dome, said lower and upper manifolds closed therebetween, substantially as and for the purpose set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
